How this service works
Domain in, technology stack out. Confidence and evidence for every hit. Pay per call in USDC over x402. No signup, no API key.
Output
Returns a list of detected technologies for the given domain, each with a name, category (e.g. CMS, analytics, CDN, framework), version if detectable, a confidence score, and supporting evidence for the detection hit.
Example use cases
Competitive tech stack research
“What technology stack is stripe.com running? I want to know their frontend framework, analytics tools, and any CDN they're using, with confidence scores for each.”
Sales lead enrichment
“Before my call with this prospect, can you detect what technologies acmecorp.com is using so I know which platforms they're already invested in?”
Incremental re-scan for stack changes
“I last scanned example.com on 2024-11-01 and found React, Nginx, and Google Analytics — can you re-scan it now and tell me if anything has changed or been added?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/universal-analytics?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need per-call, no-signup technology fingerprinting with structured confidence and evidence output, paid anonymously in USDC. It is ideal for one-off lookups, agent workflows that enrich CRM leads, or competitive intelligence pipelines that don't warrant a subscription. The optional `previous` field enables incremental change detection, making it suitable for monitoring workflows as well.
Side effects
- Invalid or unreachable URL — endpoint cannot fetch or fingerprint the domain
- Payment failure over x402 — USDC transaction not completed, call rejected
- Domain returns no detectable signals — empty or minimal technology list returned
- Malformed input schema — missing or oversized URL field causes rejection
- Rate or quota limits on the underlying scanning infrastructure
